'To ALL WHOMLIT MA-Y' coNoaRN; n i Be it known that we, WILLIAM H.DoANn, Gnamrr. V. OaroN, `and WILLIAM E. LONDON, of Cimzinnati,v

l ,Haniilton county, State of Ohio, have invented a new and improvedAUpri'glitfrSlfulping, Co'rnering, and Mould- -ihg Machine.;4 and we dohereby declare that the following is a full, clear, ander-actdescription thereof, reference being' had to the accompanying drawings,making a part'of.thisnspecication, in whinh.-

First, lina' cutter-head'formed in two parts independent ofthefguid'collars g,'s' *iasy to receive bits of various lengths, 'and witha rectangular eirtension to support the cutters and break-irons;secondly, in the use i of adjustable break-irons in'conjunction -withmoulding-cutters, whichfarehc'liihped and held in place upon a studbetween movable collarsfor the purpose of preventing theslivering 4thestuiv while cutting, and also for regulating lthe depth of cut, as willbe hereinafterv` described ;t hirdly, iii providin'gi,for supportinglavertically adjustable shield or guard upon the surface of the table, andnear thoputters, lin such manner that this Y"shieldshall n ot be inthe'way of' the stu' during the action of the cutterspaiiid in' suchmanner as to dispense `-with theuse of alframe overhanging forsupporting such shield, asfwill behereinafter described..

ATo enable others skilled in' theart to understand our invention, we-vwill jgdescribe its'construction andl 4o eration.

y p The table consists oil a horizontal top A, upon which the stu' isplace to-b'e cut, anda `frame, B, which supports saidtop and also thecutter-spindle. The spindle'G is supported'atlits'l'ower conicalend upona step, a, and near its upper end by means of a journal-box, Zz, whichlatter is secured rigidly to the frame or stand B. The

- step a is constructed with al male screw-thread upon it for receivingtheIw'heels'ID and E," the hubs of which beur p against theends ot' abox, c, through which the screw-step a is allowed to in ove up and downloosely. The handwheel D, which rests upon the top of the box c, -isused for raisingorlowering the step and its spindle,'and the hand-wheelE is used for securing the step and the wheel D rigidly in place afteradjustment. The keyltenon "ci, which .projects from the box c, andenters a vertical groove yin thescrew-step a, as-shou'n in iig. 2,prevents the step from turning with the wheelD. The wheel E serves as akind of jam-nut for the step and upper wheel, and holds these parts sotight that-the rotation'of 'the spindle and ,jarring-lof *the machinewill not allow wheel D to become loose. Betweenthe step a and upperbearing b a belt-drum, F, is secured to the spindle C,

- by i'ineans of .which motion is communicated to the latter from 'anyconvenient motor. The upper end of the spindle C has a screw-holemadecentrally in it for receiving a male-screwz,"d, whichis forled onthe low'er end of the stud g. This allows-of. the use of -studs orcutters of di'erent lengths and kinds upon a single spindle,

and obviates thel necessity of 'relnoving the spindle when acutter-head' is to be changed. The stud g is constructed with acylindrical collar or flange, g', upon it, which forms the gauge againstwhich the stuii' is held during the cutting operation. Onthe upper endof.,the stud g'a screw-thread is cut-'for'receiving a nut, g. Betweenthis nut g2 and the gauge-collar g1, two loose collars h la,constituting an independent',v cutter-head, "formedin two parts, and twocutters 7c k, are confined, as shown in i'igs. '3 and 4. These twohalves, h, are made alike, and have each a rectangular extension, k',for lateral support of the cutters, and also two grooves, t'z', intowhich the ends ofthe cutter-blades 7c 7c iit. These grooves aremadesli'ghtly taperin g so as to cause the tapering or slightly bevelledends of the blades c to fit snugly in their places'when the nut g2 istightly tied up. Each blade k has a break-iron, 7c', secured to itsinner side by means of screwsl]` which pass through oblong slots madethrough` the blade k, and enter the break-iron. Thlese caps orbreak-irons are also supported by being firmly clamped aga-inst therectangular extensions h. Thus the latter can be adjusted and set as maybe required.

These ,break-irons have those edges nearest the cutting-edges of blades7c' clb'e'velled so as to forni double heels, therefore, for breakingthe chips and'preventing slivering or tearing of the wood. Therectangular Vmoved around the axis of the cutter-head, and alsoVadjusted vertically, substantially 'as extensions I/of the collarsh'serve as side bearings for thaeutters,and prevent lateral vibrationthereof. The cuttcrs'lc c can be readily removed by unscrewing4 the nutgiand slipping off tlleuppcr collar It, and cutters' of diiferent siaesintroduced in their places.V By having both collars 7thremovable,'others'otl different sizes' can be usecl intheirV steadwithout the necessity of changing the stud which receives said collars..Anopen-v Work shield, G, is arrangedover the cutters to prevent'injuryto the hands of the Workmen. This shield is con neetedby means ofasleeve and set-screw to a post, m, and Vmay be raised and lowered andsecured at any desired height above the surface of the table-top, t Thepost m issccured to a horizontal bracketym", whiclris formed on aflanged ring, y), that is-let into the annular recess which is formed inthe table-top A, concentric toV .the axis ofthe spindle C. "lIhis ring pis held down in place by means o'ifanother ring, r, which is. alsorecessed into. the table-top, as shown in figs. 2 and 7. 1 Thenppersurfaces of both rings are Hush ivith the surface of theY tabletop, soas not to bein the way of the stui' which is presented to thc cut' is.The inner ends of the raised bracket mare rounded, as shown in fig. (i,`and constitute abutments against which the stuE-impinges, so

4that said bracket, with its ring p; will be niovedraroulnd in advanceof the stuff, and will consequently not be in the way. ly thisarrangement a safety-shield caribe supported upon the table-top Withoutthe employment of an auxiliary frame. As hitherto, the shield willalways be arranged conecntri'ca-lly over the cutter-stud, and willprotect the hands of the operator fromcoirtact' with the rotary cutters,'The machines are constructed with a single spindle, or with twospindles to rotate in opposite directions, to'suit the lnature; of thework to be perf formed'. l 1 t A Having thus described ourinventiori,what we claim as new, and desire to .secure by Letters Patent, is- 1.The combination of the adjustable break-irons t c with the cutters k 7c,and the removable collars L h, all constructed and arranged in themanner and for the purpose desribed.

2. The application of the shield G- to a post, m, which is allowedtorevolve around the cutter-head, substantially as described. y y A i i 3.Sustaining the safetyshield Gr upon the table-top A,` by'means whichwill adinit of said shield being described. y
